It has now been decided (see Biol. Centr.-Amer., Lepid. Ehopal. 

 p. 2) that the Papilio plexipptis of Linnaeus must be the species 

 which has been long known under the name of Danais archippus of 

 Eabricius and not the Indian species. Although the authors of 

 the Lepidopterous portion of the ' Biologia ' have in this in- 

 stance departed from their usual plan of adopting the name re- 

 specting which there could be no question in preference to that 

 of which there might still be the shadow of a doubt, I quite think 

 they are justified in so doing, by the strong circumstantial evi- 

 dence in favour of the adoption of the name D. plexippus for the 

 New- World insect.

Nearly the whole of the Butterflies collected by Lord "Wal sing- 

 ham were provisionally named for him by Mr. Elwes : the pre- 

 sent species I find labelled as the S. hoopis of Behr ; but of that 

 species its author says that it is " only distinguishable from 

 Nepliele by the absence of eyes on the underside of the bind 

 wings." An examination of the five examples before me gives the 

 following results : — 1 S with 6 distinct ocelli on under surface 

 of secondaries ; 1 with 6 less distinct ocelli, the first and third 

 without pupils ; 1 with 6 still less distinct ocelli, the first to fourth 

 without pupils ; 1 with 6 distinct ocelli, but the four first and 

 the sixth extremely small ; and, lastly, 1 $ with six punetiform 

 ocelli, the pupils having only a black edge. Ail these specimens 

 agree perfectly with Boisduval's S. ariane, described as having 

 " une rangee irreguliere de six petits yeux noirs, a pupille blanche 

 et a iris fauve, groupes trois par trois, et plus ou moins bien 

 marques"*. 



* Of the female Boisduval says, " les petits yeux du dessous des ailes in- 

 ferieures beaucoup moins visible que dans les males,"
